Launcher speeds excrutiatingly slow as well as having account issues.

Launcher itself is excrutiatingly slow with download speeds. it took me well over 3 hours to download version 1.19.3 on a network thats going 20mb/s. not only is account control bugged as all hell, but when eventually logging into minecraft, it says invalid sessions. mid you i tried this on multiple versions of the launcher on multiple apps and even a linux distro. ive expressed extreme concern over the issue when the bootstrap is getting updated, as clicking cancel does nothing whatsoever. the entire launcher is messed up bad. its not my account because i know its not. not only is this a severe account security issue, but it's practically unplayable.
